Discharge requirements of Yuasa batteryDischarge requirements of Yuasa battery
There are certain requirements for charging and discharging of Tangqian battery, especially in harsh working environment. When the ambient temperature is higher than 25 ℃, the battery capacity is higher than the rated capacity.
When the ambient temperature is lower than 25 ℃, the battery capacity is lower than the rated capacity. The capacity changes with the change of temperature. The maintenance personnel must carefully adjust the discharge current of the battery according to the actual temperature change, and control the temperature of the battery to keep it in the range of 22 ℃ ~ 35 ℃. High temperature environment is the main reason that the actual life of battery can not reach the design life.
When the temperature of Tangqian battery increases by 10 ℃, the acceptance of charging current under constant voltage will be doubled, and the battery life will be shortened due to the increase of total accumulated charge of overcharge. The basic requirements for the operation and maintenance of UPS power supply battery are as follows: in order to make the battery always be fully charged without overcharge, more than 80% of the rated capacity should be released when the battery is supplied to the load separately.
The discharge tester is specially designed for checking discharge experiment, capacity test, daily maintenance, engineering acceptance and other tests of DC power supply load capacity of battery pack. The power consumption part of Tangqian battery discharge tester adopts new PTC ceramic resistor as discharge load, which completely avoids red heat phenomenon, and is safe, reliable and pollution-free.
The whole machine is controlled by microprocessor, LCD display and Chinese menu. It has novel appearance design, small size, light weight and easy to move. After various discharge parameters are set, the whole constant current discharge process is automatically completed. Fully intelligent. The whole discharge process is safer. It is especially suitable for battery acceptance, check discharge test and regular deep discharge.
